A reduction is made in computational complexity for cancellation of multipath interference. A delay profile creator creates a delay profile upon activation of a multipath interference canceller. When the number of taps of the multipath interference canceller is not less than a predetennined threshold, a number-of-samples controller extracts sample data corresponding to a chip rate being a sampling rate for cancellation of interference, from sample data sampled by an A/D converter. A channel matrix generator generates a channel matrix on the basis of the sample data thus extracted. A weight matrix generator generates a weight matrix on the basis of the channel matrix generated by the channel matrix generator. An interference canceller cancels multipath interference by multiplying data on channels by the weight matrix.
